Lead type refers both to the metal and to the whole printing technique based on movable type cast in an alloy of lead, tin and antimony. Introduced in Europe by Gutenberg around 1450, the process dominated printing for more than five centuries.
Where to see it
Lead type can be seen in traditional typography workshops and at letterpress printers, who still use it for announcements, cards and posters. Much of typographic vocabulary comes from it, from point size to the type case and leading, which originally referred to a thin strip of metal slipped between lines.
Why this detail matters
Lead type remains a reference for understanding typography:
- Most typographic notions, such as point size, sidebearings or leading, come directly from the physical constraints of lead type;
- Letterpress printing leaves a slight impression in the paper, sought after today for its handcrafted and precious character;
- Many digital typefaces are reinterpretations of typefaces originally designed for lead type.
